Isaiah 25:10-12

10The hand of the Lord will rest on this mountain; but Moab will be trampled in their land as straw is trampled down in the manure. 11They will stretch out their hands in it, as swimmers stretch out their hands to swim. God will bring down their pride despite the cleverness of their hands. 12He will bring down your high fortified walls and lay them low; he will bring them down to the ground, to the very dust.
